Description

Metadata interface to generate symbolic and hash ID tags for media processing steps.

Functionality is provided to identify a point in the processing chain for sake of error reporting and unit testing; moreover, identifying information can be chained and combined into a systematic hash key, to serve as foundation for a stable cache key.

Todo:

WIP-WIP as of 10/2024 this is a draft created as an aside while working towards the first integration of render engine functionality //////////////////////////////////////////////TICKET #1377 : establish a systematic processing identification

Remarks

the essential requirement for a systematic and stable cache key is

• to be be re-generated directly from the render node network
• to be differing if and only if the underlying processing structure changes
